Also, the increase in moisture throughout the atmosphere (enough to rain a little early) indicates that there is plenty of moisture available. Again, sooner than I first thought.
Sunday still looks wet for the most part with showers and thunderstorms likely throughout much of the day. The threat will end by 6 pm as temperature cool off into the 60s and even drop into the upper 50s by Monday morning.
Memorial Day itself looks mainly dry with only a slight chance for a shower, or some drizzle and that is mostly early in the morning. But the presence of a lot of clouds will dampen the mood and keep it much cooler.
How much cooler? If it stays cloudy all day, it may only reach 65, but with a little sunshine/thinner clouds we'll reach 74 (which is what I think will happen).
The cool front will then lift back north and east bringing in much warmer air for Tue ahead of yet another front which will cool things off for the rest of the week. The big problem for Wed and beyond is what to do with the remnants of Tropical Storm Alberto. Since the weather pattern has been rather slow to change and systems seem to want to linger in the eastern US this month, this tropical system and its moisture may linger around the east for up to a week. This could lead to a very wet period from later Wed through the first weekend in June.
At the least, enjoy today!
